I used to atleast once a week until I felt like my batteries were getting really drained,, noticed on first few sets before things got to heavy,, my ego used to really get best of me on this lift,, I wanted big numbers then one day pulling heavy I popped out my sacrum bad,, was my second back injury,, after all the dumb stuff I'd done thru out my life I had never hurt my back,, it wasn't the lifts fault tho,, I think they are great depending on what your doing, but you can get big and strong as f with out doing a lift that a few inches the wrong way can screw you for life,, or just stay 315 or less I'm easing my way back up,, I noticed mechanical positions aren't as compromised in one of the triangle bare deals you stand in tho to., might be another route for you to go, and if you going to frequently do them keep the volume low and consistent and your body will adapt to the strains instead of going HAM and getting drained as hell,, heavy deads are hard work!! Sorry for book reply, and excuse grammar!
